The Dell Medical School and its teaching hospital, Dell Seton Medical Center, are part of a vibrant health district that is one of Austin’s largest development projects. The 16.2-acre development is located in central Austin on the University of Texas campus—serving the faculty, staff, students and visitors of the Dell Medical School and setting a new image and ecological performance standard for the UT Austin landscape.

The design process for the Dell Medical District landscape was a seamless extension of two previous years of planning by Sasaki and the consultant team. The team had already developed the 2012 Campus Master Plan, the 2013 Medical District Master Plan, and the 2014 UT Austin Campus Landscape Master Plan and Design Guidelines. The development of the Dell Medical District landscape plan employed the same broad-based, inclusive process that characterized the preceding master plans, furthering established collaborations with those responsible for the development and maintenance of the campus landscape.

2012到2014年期间制定的总体规划方案皆以德州大学独有的历史文脉出发，在深度和广度上对校园未来的拓展和优化进程奠定框架。以医疗卫生为焦点的校区成功落实，充分反映了总体规划的全面愿景——即打造一个融会贯通、满足医疗卫生用途的区域，复兴沃勒溪（Waller Creek）走廊，以及加强区域与奥斯汀市的连接。 曾被荒废的沃勒溪重新被视为校区的重要资产和开放空间，发挥关键的连接作用。恢复沃勒溪的医学区段是将其纳入为广域校园景观的首要一步，这对景观的视觉美感和实际功能都是必不可少的举措。
▼沃勒溪走廊，建设前的沃勒溪走廊是一个被人遗忘并且未被开发的自然资产，走廊上曾经遍布的入侵植物现已被移除，为本土滨水植物群落提供了发展空间，the Waller Creek corridor, prior to development, the Waller Creek corridor was a forgotten and unexploited natural asset, also, the corridor was overgrown with invasive vegetation which was removed to encourage a native riparian savanna plant community
The 2012-2014 University master plans established a framework for campus growth and improvement unique in the campus’s history in scope and depth. The successful implementation of the Health Campus realized the master plan’s comprehensive vision for a coherent district of health-related uses, the reclamation of the Waller Creek corridor, and the strengthening of connections to the City of Austin. Once neglected, Waller Creek is now celebrated as a campus asset and important connective open space. Reclaiming the medical district segment of the creek is a first step towards reintegration of this important visual and functional landscape feature into the larger campus.

Restoration of Waller Creek was an 18-month long process that included establishing a reference plant community at a nearby Nature Conservancy preserve, the removal of invasive species, stream bank stabilization and the re-vegetation of diverse native riparian and upland communities. The work involved the creation of rain gardens and the remediation of soils for significant areas. Once established, most areas of the campus landscape will not require irrigation.

Streetscapes and two plaza spaces serve as social gathering spaces. One plaza is located between the clinical and research facilities and connects Trinity street to Red River Street encourage social engagement and connect the campus to its surrounding urban environment. The Medical District landscape plan is designed to enhance ecosystem services and to be a model for a resilient and affordable-to-maintain landscape. Stormwater management features were designed as site amenities to connect visitors to the local climate and hydrology—through a combination of rain gardens, pervious pavers, rainwater harvesting, and a green roof.

The University’s commitment to the health and well-being of the campus community drove the project to undertake the relocation of 14 mature Live Oak trees. Live Oaks are emblematic features of the historic Beaux Arts main campus, beloved for their beauty and the many ecosystem benefits they provide, including welcome shade in the Austin climate. The transplanted Oaks extend the best aspects of the historic campus to the new Health Campus district. The majestic trees confer instant grace on developed areas, offsetting the presence of large heath care facilities.

The Dell Medical District landscape sets a new standard for sustainable site development on the UT Austin campus, achieving SITES Gold Certification. The reduction of water consumption, improved stormwater quality, reduced soil erosion, increased habitat value, and enhanced landscape resilience are tangible benefits of the new landscape. The overall design vision is expressed in the new open, inviting, and people-centered campus, connected to its environment and community. On the new campus, people and the environment work together as a functioning system, focused on improving health.
